Hello,
As you are preparing for the air force best is to do B.Tech as it will give you the widest options in airforce. For B.Tech you have to give the JEE exam or other state engineering exams. You can also do engineering from a private university. Don't pursue B.A. As it limits your option to only CDS.

Robotics and artificial intelligence, biotechnology, nanotechnology, electrical are some branches of tremendous scope in the future.
